Ingredients

Scale
  • 1 package (12 rolls) canned cinnamon rolls with icing included
  • 1 cup whole milk or 2% milk
  • 3 large eggs, beaten
  • 1/4 cup packed brown sugar
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 2 tablespoons melted butter
  • Optional: 1/4 cup chopped pecans or walnuts
  • Optional: pinch of salt
  • Optional dairy-free alternatives: almond milk or oat milk

Instructions

  1. Preheat oven to 350°F (175°C).
  2. Lightly grease a 9×13-inch casserole dish with butter or non-stick spray.
  3. Cut each cinnamon roll into 4 pieces.
  4. Arrange the quartered cinnamon roll pieces evenly in a single layer in the casserole dish.
  5. In a medium bowl, whisk together eggs, milk, brown sugar, vanilla extract, and ground cinnamon until smooth and slightly frothy.
  6. Pour the custard mixture evenly over the cinnamon roll pieces, ensuring all pieces are coated.
  7. Drizzle melted butter over the top.
  8. Cover the dish tightly with aluminum foil and refrigerate for at least 4 hours or overnight.
  9. Bake covered for 25 minutes, then remove foil and bake for an additional 15-20 minutes until golden and bubbly and the center is set but still soft.
  10. Drizzle the included cinnamon roll icing over the hot casserole.
  11. Let cool slightly before serving.

Notes

[‘Do not skip the soak time; refrigerate at least 4 hours or overnight for best texture.’, ‘Use room temperature eggs and milk to avoid curdling.’, ‘Cutting rolls into quarters helps soak up custard evenly.’, ‘Watch baking time closely; if casserole browns too fast, tent with foil.’, ‘Optional: add chopped nuts before baking for crunch.’, ‘Optional: add a pinch of nutmeg or cardamom for extra flavor.’, ‘Use glass or ceramic pans for even baking; metal pans may cook faster.’, ‘For dairy-free or vegan, substitute eggs with flax eggs and milk with almond or oat milk.’]
